actually the 87 intercooler's and all the piping are different from the 88's and up. the 87 intercooler and piping has alot more 90 degree bends then the smother 88's so all you need is a 88-91 intercooler and your set. my ma70 was actually an early 87 built in 86 and alot of stuff was different form the 88's and up.
